Patented Dec. 23,1913.

Application filed September 13, 1913. Serial No. 789,613.

To all whom it may concern Be it known that I, VVILLIAM A. PENFIELD, acitizen of the United States, residing at Meriden, in the county of NewHaven and State of Connecticut, have invented a new and usefulImprovement in Air-Distributors for Central-Draft Lamps; and I do herebydeclare the following, when taken in connection with the accompanyingdrawings and the characters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part of this application, and represent, in--- Figure 1 aside view of an air distributor for central draft lamps constructed inaccordance with my invention and shown as located in the upper end of acentral draft tube. Fig. 2 a vertical sectional view of the same. Fig. 3an underside view.

This invention relates to an improvement in air distributors for centraldraft lamps, and is an improvement on the device shown and described inUnited States Patent No. 529,496 dated November 20, 189st. In the deviceshown and described in the said patent, a single ring-like deflector wasarranged near the top of the distributor between two outwardly thrownribs or shoulders.

The object of this invention is to provide an air distributor of thetype shown in the said patent, which will have all the advantages ofthat construction, and have the further advantage of supplying a currentof air across the top of the flame, so that the flame will be kept down.As heat about the burner increases, the tendency of the flame is tocreep up and smoke; and the invention consists in the constructionhereinafter described and-particularly recited in the claim.

In carrying out my invention I form the perforated distributor 2 with aclosed end 8, and below and near the upper end I locate an upper annulardeflecting ring or collar l between outwardly extending annular ribs 5and 6, and below the ring is a lower annular deflecting collar or ring 7also located between annular ribs 8 and 9. The space between the tworings is suflicient to include two or more rows of perforations, so thata current of air may pass outward from the central draft tube 10 betweenthe two rings as well as below the lower one and above the upper one.The distributor is supported in the central draft lamp so that the lowerring stands well above the upper end of said central draft tube and outof normal contact with the wick, and so that the air below the lowerflange is distributed above the end of the wick. The air distributor maybe supported in any desired manner, for instance, as shown in Fig. 1, byslight projections 11 thrown out at intervals and adapted to rest uponthe upper end of the central draft tube. Preferably and as herein shown,the upper ring is slightly larger in diameter than the lower ring. Byproviding two rings three jets of air are thrown outward horizontallyagainst the flame, tending to increase the whiteness of the flame andkeep the flame down so that the liability to smoke is somewhat avoided.By employing two rings, a heavier oil may be used than is possible withburners of usual construction.

I claim The herein described air distributor for central draft lampshaving its upper end closed and provided near its upper end with anupper air deflecting ring and with a lower air deflecting ring, thesides of the distributor perforated above the upper ring between thrings and below the lower ring, and means for supporting the distributerin the upper end of a central draft tube whereby the lower ring is heldout of contact with the wick, and whereby the air passing through thedistributer is distributed in three jets.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
